Table 4 Recovery (g/g) of internal markers in feces for each bermudagrass hay treatment (n = 6)

From: Comparison of acid-detergent lignin, alkaline-peroxide lignin, and acid-detergent insoluble ash as internal markers for predicting fecal output and digestibility by cattle offered bermudagrass hays of varying nutrient composition
